ToughMet® is Brush
Wellman’s solution to your severe service material problems. By applying
our EquaCast™ process, tailored alloying additions and spinodal hardening
technology, we have engineered ToughMet® to provide attributes beyond
those typically found in a high-strength copper alloy.
- Exceptional resistance
to corrosion and cavitation
- Outstanding lubricity
and durability in demanding applications
- Highly uniform composition
in all product forms
ToughMet® 2 in
the cast and spinodally hardened (CX) condition exhibits tensile strength
in excess of 105 ksi and hardness exceeding HRc 27 with excellent machinability.
This Copper-9Nickel-6Tin alloy combines low coefficient of friction with
wear resistance.
